1 Functional characterization of 40 CYP3A4 variants by assessing midazolam 1"-hydroxylation and testosterone 6beta-hydroxylation. Testosterone cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 In this study, we characterized wild-type CYP3A4 and 40 CYP3A4 variants, including 11 new variants, detected among 4,776 Japanese individuals by assessing CYP3A4 enzymatic activities for two representative substrates (midazolam and testosterone). Testosterone cytochrome P450 family 3 subfamily A member 4 Homo sapiens

4 The kinetic parameters of midazolam and testosterone hydroxylation by wild-type CYP3A4 and 29 CYP3A4 variants (Km , kcat , and catalytic efficiency) were determined, and the causes of their kinetic differences were evaluated by three-dimensional structural modeling. Testosterone cytochrome P450 family 3 subfamily A member 4 Homo sapiens
